As detailed in FIG. 9, the latching mechanisms 90 secure the first tabs 318 of each side wing 80 to the cover 76. The standoff 290 may serve as a buffer or stop to contact the flange 250 at respective sides 246 and 247 of the cover 76.

FIGS. 6 and 10 show locked and unlocked positions (in solid and hidden lines, respectively) of the cover 76 and the side wings 80 are in their deployed configurations. In the deployed configurations, the cover 76 is angled upwardly from its vertical position by angle β of about 45 degrees from its position of FIG. 8. As shown in FIG. 6, the side wings 80 are angled outwardly from their folded positions of FIG. 8 by about 90 degrees. As shown in the deployed configurations of FIGS. 6 and 10, the second side 300 of each side wing 80 is positioned adjacent the flange 250 at the respective sides 246 and 247 of the cover 76. As detailed in FIG. 10, the latching mechanisms 90 secure the flange 250 at the second side tabs 320 of each side wing 80 to the cover 76.

With further reference to FIGS. 6-10, each latching mechanism 90 illustratively includes a handle 325 received within a recess 327 formed in the outer surface 245 of the cover 76. A lever arm 329 is coupled to the handle 325 and is configured to pivot about a pivot pin 330. An adjustable clamp 332 is supported at a first end of the lever arm 329, while the handle 325 is coupled to the second end of the lever arm 329. The clamp 332 includes a threaded stud 334 cooperating with a nut 336 for adjusting the position of a resilient bearing member 338. The latching mechanism 90 defines an over-center clamp by the handle 325 and the lever arm 329 being positioned on opposite sides of the pivot pin 330.

The latching mechanism 90 is in a locked or clamped position when the handle 325 is substantially parallel to the outer surface 245 of the cover 76 (shown in solid lines in FIGS. 9 and 10). FIG. 9 shows the stowed configuration where the clamp 332 in the lock position secures the first tab 318 of the side wing 80 to the body 244 of the cover 76. FIG. 10 shows the deployed configuration where the clamp 332 in the locked position secures the second tab 320 of the side wing 80 to the body 244 of the cover 76. By the user inserting a finger within an opening 340 adjacent to the handle 325, the handle 325 may be lifted or pulled outwardly away from the cover 76 such that the handle 325 and the lever arm 329 are pivoted about pivot pin 330 (to the position shown in hidden lines in FIGS. 9 and 10). Once the cover 76 and cooperating side wings 80 are positioned as desired (i.e., stowed or deployed), the handle 325 may be pushed back into the recess 327 and flush with the outer surface 245 of the cover 76. The lever arm 329 rotates such that the clamp 332 secures the cover 76 to the respective side wing 80.

An illustrative method of accessing an interface panel of signal interface assembly 12 comprises the steps of releasing the latching mechanisms 90 securing cover 76 to the side wings 80 (FIGS. 8 and 9) when in the stowed configuration. In the stowed configuration, the cover 76 extends substantially parallel to the side wings 80 to provide a flush outer surface to the support 44. To release the latching mechanisms 90, the handles 325 are pivoted outwardly from the recesses 327 of cover 76. In response, the lever arms 329 unclamp the cover 76 from the first tabs 318 of the side wings 80. Next, the cover 76 is pivoted upwardly about horizontal axis 100, illustratively by angle α to the fully raised position shown in FIG. 22. The detent assemblies 254 are configured to releasably hold the cover 76 in this position.

The side wings are 80 are then pivoted outwardly about vertical axis 86 into the deployed position shown in FIG. 6. The step of pivoting the side wings 80 outwardly includes biasing the side wings 80 through a spring 282. The cover 76 is then lowered (pulling down will release the detent assemblies 254) to the deployed position represented by angle β in FIG. 22. In the deployed configuration, the cover 76 extends substantially perpendicular to the side wings 80 and at an acute angle relative to vertical. In this position, the flange 250 of the cover 76 receives the second tab 320 of each side wing 80 in a nesting arrangement. Next, the latching mechanisms 90 are engaged to secure the cover 76 to the side wings 80. More particularly, the handles 325 are pivoted inwardly into the recesses 327 of the cover 76. In response, the lever arms 329 clamp the cover 76 to the second tab 320 of the side wings 80.
